CHESTNUT BARK DISEASE, 447 
which contained trees over one foot in diameter, 845 trees over 
one foot in diameter were marked for removal in the winter 
of 1912-13, besides numerous trees and sprouts of less diameter. 
This same winter, in all the woods on the estate, there were 
2,200 trees over one foot in diameter that were marked for 
removal. In this experiment it was not attempted to remove 
the bark from the stumps. In certain badly diseased spots 
where the stumps were examined, it was found that perhaps 
30 per cent. of them showed some signs of the fruiting stage 
of the fungus the following summer. 
The second experiment was started in the fall of 1911, at the 
Portland state forest. Here certain designated wood lots, eight 
in number, were gone over, and all trees and sprouts showing 
cankers were noted and marked for removal. These were 
removed during the following winter, and the wood and bark 
disposed of. A partial reéxamination was made the next spring, 
to determine how effectively the work was done. In spite of 
the fact that the preliminary examination had been carefully 
made by two well-trained scientific men, and the ground had 
again been gone over by a practical man who removed the 
marked trees and any others he saw to be infected, it was found 
that some of the diseased trees had been overlooked. Six other 
lots in these woods were also examined, and the blighted trees 
counted, but not removed, these serving as a check to determine 
the benefit of removal in the other lots. 
All of these lots were reéxamined in the fall of 1912, and 
the trees removed that winter, as before, from those lots 
reserved for removal. It is expected to keep up this experi- 
ment for several years, if warranted by the results or the preva- 
lence of the blight. As yet it is too early to determine the 
effect of the removal of the trees on the spread of the blight 
by comparison with the check lots. So far as the second year’s 
results go, however, there were proportionately just as many 
newly blighted trees found in lots where all had been removed 
the year before as in the lots where all diseased trees had been 
left. 
RECOMMENDATIONS FOR CONNECTICUT. 
We are not advocating concerted action throughout the state 
to attempt control of the disease by the cutting out method. 
We are only rarely advising this method, in certain districts
